Changes in the incidence, cause and severity of cervical spinal cord injuries over the last 30 years and the implications for biomedical research – lessons learnt from the Tetragrip project

Q: What does this research mean for the field?

Over the past 25 years, individuals sustaining spinal cord injuries have become older, with less severe injuries more commonly resulting from falls rather than road traffic accidents, significantly impacting research recruitment and clinical services. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To examine changes in the demographic characteristics, causes, and severity of cervical spinal cord injuries over a 25- to 30-year timeframe and evaluate their impact on clinical research recruitment and healthcare delivery.
Analyzed trends in participant recruitment challenges encountered during the Tetragrip project compared to comparable interventions conducted 25 years earlier.
Investigated longitudinal shifts in patient age, underlying mechanisms of injury, and injury severity over a 25-year period.
Individuals sustaining cervical spinal cord injuries over the 25-year interval were notably older compared to past cohorts.
Primary causes of injury shifted toward low-energy mechanisms such as falls rather than high-energy motor vehicle collisions.
Overall injury severity decreased over time, resulting in recruitment shortages for trials requiring severe, complete tetraplegia.

Implication

Epidemiological analysis demonstrates older age, reduced severity, and increased falls among spinal cord injury cases, indicating major shifts for clinical trials and care.

Abstract

The Tetragrip project to restore hand function for people with tetraplegia highlighted that participant recruitment was far more difficult than when we undertook similar work 25 years ago. Further investigation showed that over those 25 years people sustaining spinal cord injuries were older, their injuries were less severe and more likely to be as the result of a fall rather than a road traffic accident. This has major implications, not only for research, but also for clinical services.
